The thread overview page shows an overview of threads for a selected forum showing the initial post message of the threads.
 
Adding a New Topic from the navigation bar is making a new entry in this thread overview. The first post and answers to it are composed into a thread showing up on this page. Clicking on a thread will open the Thread reading page where all corresponding posts are presented in a threaded list.
 
New threads you didn't read so far are marked with a "new" indicator. Reading a thread means to open the Thread Reading page for a particular thread.
 
The navigational bar contains links to:

• Return to the "Forums" overview page
  
• Create a new thread writing a "New Topic"
  
• Opening the forum "Search" page
  
• "Mark all thread as read" to mark all "new"-entries as read (only available if there are some)
  
• "Prev Page" and "Next Page" to navigate, if there are many entries.
  

Here's a brief explanation of the field items in the content section:

• Thread: The subject line of the initial post of a thread.
  
• Author: The author who started the thread.
  
• Posts: number of posts in the thread.
  
• Hits: number of reads of the thread by other users
  
• Lastpost: date of the last post in the thread (with author of last post, which can be hidden)
  

Below the content table there's a select-box to change the number of shown rows.
